We're dividing 12970844 by 349 
We want to figure out the number of times 12970844 can be divided by 349.

Going ahead to step 1:
349 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 349

On to step 2:
The number 349 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 349

Moving on to step 3:
The number 349 fits into 129 0 times, leaving a remainder of 129.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Fetch the next digit (7) from the dividend, attach it to 129 and continue: 1297 / 349

Moving on to step 4:
349 goes into 1297 3 times with a remainder of 250.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 250 after subtracting 1047 from 1297.
Take the next digit (0) from the dividend and append it to 250, then repeat: 2500 / 349

Step 5:
349 goes into 2500 7 times with a remainder of 57.
The next digit of our result is 7. 
Result so far: 37.0
If we take 2443 away from 2500, we end up with 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 349

Let's proceed to step 6:
349 can be fit into 578 1 times, resulting in a remainder of 229.
Write down 1 as next digit of the result. 
Result so far: 371.0
The remainder is 229 after subtracting 349 from 578.
Take the next digit (4) from the dividend and append it to 229, then repeat: 2294 / 349

Moving on to step 7:
When dividing 2294 by 349, we get 6 with a remainder of 200.
The number 6 becomes the next digit in our result. 
Result so far: 3716.0
Subtract 2094 from 2294 to get 200.
Bring next digit (4) of the dividend behind the 200 and repeat the process: 2004 / 349

On to step 8:
2004 divided by 349 is 5 with a remainder of 259.
The next digit of our result is 5. 
Result so far: 37165.0
If we subtract 1745 from 2004, we get 259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

Moving on to step 9:
If we divide 2590 by 349, we get 7 and a remainder of 147.
Use 7 as the next digit of our solution. 
Result so far: 37165.7
Subtract 2443 from 2590 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Advancing to step 10:
When dividing 1470 by 349, we get 4 with a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 37165.74
Deduct 1396 from 1470 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
When dividing 740 by 349, we get 2 with a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 37165.742
If we take 698 away from 740, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 12:
The number 349 fits into 420 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 37165.7421
The remainder is 71 after subtracting 349 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 13:
The number 349 fits into 710 2 times, leaving a remainder of 12.
The next digit of our result is 2. 
Result so far: 37165.74212
If we subtract 698 from 710, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
If we divide 120 by 349, we get 0 and a remainder of 120.
Write down 0 as next digit of the result. 
Result so far: 37165.74212
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 15:
When dividing 1200 by 349, we get 3 with a remainder of 153.
The number 3 becomes the next digit in our result. 
Result so far: 37165.7421203
Subtracting 1047 from 1200 leaves us with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Moving on to step 16:
349 can be fit into 1530 4 times, resulting in a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 37165.74212034
Subtract 1396 from 1530 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

The final outcome is 37165.74212034, with a leftover of 1.34e-07.
